HEATING-DRUM.

SPECIFICATION formingof Letters Patent No. 662,364, dated November 20,1900.

Application tiled May 10, 1900. Serial No. 16,171. (No model.)

T0 all whom, it may concern:

Be it known that I, JAMES MAHEDY, a citizen of the United States,residing at Kellerton, in the county of Ringgold and State of Iowa, haveinvented certain new and useful Improvements in Heating-Drums; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to heating-drums,and more particularly to thatclass of heatingdrums adapted to be connected up with the smoke-pipe ofa stove and be located in the same room as the stove or in a distantroom.

The object of the invention is to provide a device of this characterwhich shall be simple of construction, durable in use, and comparativelyinexpensive of production, special provision being made whereby thedirection of the circulation of the products of combustion may bereversed at will for the purpose of dislodging or preventing theaccumulation of soot or the like within the heating-drum- With thisobject in view the invention consists in certain features ofconstruction and combination of parts which will be hereinafter fullyset forth.

In the accompanying drawings, Figure lis an elevation of my improvedheating-drum. Fig. 2 is a vertical sectional view,and Fig. 3 is asimilar view showing the valves set to reverse the position ofcirculation of the products of combustion.

Referring to the drawings, l denotes a smoke or soot box, one end ofwhich is provided with a removable cap-2 to enable a tool or scraper tobe inserted for the purpose of withdrawing the accumulations.

2' denotes a hood, and 3 and 4 denote heatradiating tubes, whichestablish a communication between said hood and smoke-box. The hood isprovided with a transverse partition 5, below which is an inlet-oriiice6, which com mu nicates with the smoke-pipe and above which is anoutlet-orifice 7, which communicates with the chimney. The partition isprovided with two openings a b, either of which is adapted to be closedby a valve c, operated by a rod d.

c and f denote sleeves having a vertical sliding movement in theheat-radiating tubes 3 and 4. and are adapted to project up through thelower compartment in the hood and register with either one of theapertures o. h. An operating rod or pin g extends laterally from each ofthese sleeves through a vertical slot in the heat-radiating tubes 3 andet, and when either sleeve is elevated the pin or rod is turned into thetransverse or horizontal extensions at the upper end of the slot, thusholding the sleeve in its elevated position.

As shown in Fig. 2, the products of combustion from the stove enters thehood below its partition, passes downward through the tube 4, throughthe smoke box, and up through the tube 3 and the holeain the partitioninto the upper part of the hood, from whence it escapes intothe chimney.In this position the valve c is over the hole b. After the device hasbeen used some little time it is well to reverse the direction ofcirculation in order to remove any accumulations of soot and ashes, andthis is readily done by reversing the position of the sleeves c andf andthe valve c, as shown in Fig. 3.

From the foregoing description, taken in connection with theaccompanying drawings,

the construction, operation, and advantages of my improved heating-drumwill be readily apparent without requiring an extended eX- planation. Itwill be seen that the device is simple of construction, that saidconstruction permits of its manufacture at small cost, and that it isexceedingly well adapted for the purpose for which it is designed.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacriiicing any of the advantages of this invention.

Having thus fully described my invention, what is claimed as new, anddesired to be secured by Letters Patent, is-

In a heating-drum, the combination with IOO tubes and adapted to bemoved alternatelyinto engagement with the partition and in communicationwith the holes therein, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witlo nesses.

JAMES MAHEDY.
